From Fi 2' it will be observed that. theinlet mem er "14 r isopen to the" water at the bottom of the ship, andwhen' the scale isinop'eration;

valve 15 is opened, whereby thewatermay freely enter into pipe 2 andrise to the As thewateryrises to the I proper level. proper level-inpipe 2 the same counteracts or overcomes some-of the weight 'ofpipe'S'and thereby allows weightll to move'beam v i 4 pivotally. The'specificigravity of water and the metalpipe 3 is such that this action 2 1according to the amountof' water in pipe 2. i

will take pla ce to a greater or less extent,

For instance, the actibn of pipe don beam 4"will' cause ascertainmovement of beam 4 when the'vship is empty, and when the ship is beingloaded and,water'continues to rise in tube 2the action of member 3 onbeam 4 will be continued so as to show the additional weight put on theship. It is to be understood that member 3 is of iron or some othersuitable material whichhas an apreci'able weight, and which does notfloat in the water but has a specific gravity differi a I n I I u'movement as slight varlatlons 1n the water I level will not cause anyaction'of the water.

is evident that if the beam 4: is balanced with the weight 7, as shownin'Fi-g. 2 when theship, is empty, any load placed upon the ship willcausefthebeam 4 to be raised against the action of weight 7.
